To al? Vwhom itmay'oncem:

.Be it .known l`that I, 4Grensmaas J. lVrrzaL,

a citizen .ofdheUnited States, residing in New York, borough ofBrooklyn, in the county `of Kings and State of New York, have inventedcertain new and useful Improvements .in `Metallic Mattresses, of whichthe .following is a specification.

This invention relates to an improvement in metallic formed mattresses,the object of the invention being to ,provide an .improved metallicformed .mattress whichfwill ,prevent the shifting or spreading ofithehair or other stuffed mattress by locatingand holding the same securely-in .position in an effective, manner, and is in part an improvementupon .the construction shown and described in my Reissue Patent No.13,125, dated June 28, .1910. As stated in the said reissue application,one yof the .bbjecti'ons to the metallic mattresses in general use isthat the hair or other stulfed .mattresses which are ,placed thereon:shift on the same from one slde to the other Aor so spread in use thata very unsightly appearance is .the result. The present improvement,therefore, consists of a wire mattress' which is provided at each side.thereof with improved .longitudinal side guardsattached to the mattressVor bent up .therefrom and which is .comparatively sim- .ple :in itsconstruction and therefore inexpensive to ,produce .In `the drawingsaccompanyi and forming .part of this specification, lgure -1 is aperspective view of one yportion of .a bedstead illustrating one form of.this improved spring mattress having Van improved form v offside guard,the mattress in .this figure being hillustrated .as a woven wiremattress;

Fig. 2 is a. perspective view of one .portion of :a spring mattress'illustrati' a National fabrichavmgthesei proved si e-.guards attachedthereto; and ig. 3 is .a perspective view .of a ,portion of .thisimproved spring mattress. showing another form of sideguard.

.Similar characters of reference desi nate correspondin i artsthroughout the ent ii .ures ofthe drawings.

.In ig. l .the .spring mattress .is shown .as a -woven wire mattress,.while .in .Figs 2 and 3 the :mattress is, shown .as of .that .formwhichis generally .known .as a National fabric.` Each of these mattresses 2isvprovided with a side .guard -3 `attached thereto in an vimprovedmanner.

.In .the mattress shown in Fig. .1the wovenl this form of theimprovement the woven wire mattress is ,provided with bentvup sideguards Lformed of the same I.material 4as is the lbottom .4, each guardbeing `provided along .itsllower and upper edges with a reinforced orthickened portion '8, 9. The ends ofthe guard :are hooked to .theupwardly turned ,projections of the cross strip in any suitable manner,the,guard being severed intermediate its ends at Somesuitable point, asat L1, which may be at the middle -of its length-or adjacent .to oneend, as is .most desirable in',practice,.andsuch severed portions spacedapart. .Each severed ,portion 12of the sideguard is suitablybound orclam ed by some 4suitable form of :metallic binding or clamp, as 13, andbetween these severe ends one or more, preferably a plurality, spiralsprin s 14 are located to .impart a tension to t eside guards. Thesesprin maybe hooked into-.openings 15 formed 1n the .metallic rbindingsofthe side guards in any suitable manner.

'In .the `form shown in Fig. 2 .the National fabric bottom 4. is securedb. .helical springs l 116 to .theend or cross bar 7 of .the mattressframe Ain the usual manner, but in this form the side guards, which are4shown formed separately lfrom .the bottom but linked thereto along-itsedges, are secured directly to the upwardly turned projections or-angleplates v18, |19, riveted or otherwise .fastened to the end of the crossbar` 'Ilhese side guards are likewise severed intermediate .their ends,as atI .111. and spaced apart .for the lreception of helicalsprmgs 14which may be readily hooked 4to the links ofthe side guards. 'In thisfornrof the improvement, as is also the Case -with .that shown in Fig.3, the side guards, `being formed in the manner shown, require .no.metallic binding or clamping members at .the several ends thereof,since thehooks ofthe helical springs may be readily connected to :the:links or coupling membersbfthe .fabric in a .manner which will bereadily understood.

-In the form shown in 3l the sidey the guard and the upwardly turnedlprojection securedto the end or cross bar of'the mattress frame, and theother set located in a similar manner to that shown i-n Fig. 2.

1 would ordinarily occur, and so materially stiifen the side guard'and`prevent it from yielding improperly. Furthermore, by having the sideguard formed separate from the bed bottom, when'this side guard is madeof either one continuous length. orof short lengths as shown herein, thevbed bottom may;l be under a different tension from that of the sideguard. In other Words, as the bed bottom receives the Weight of the userand is usually first attached to the cross members or bars, it may beplaced under considerable tension, While, as the side guard is not sleptupon, the tension thereon may be less and the des ired tension giventhereto when it is attached subsequent to the .attachment of the bottomfabric, so that the tension given to the bed bottom fabric does notnecessarily haveto be t-lie same as that given to the side guards, sothat, ifdesired, springs of different strength or size may beusedrespectively with the bed bottom land the side guards, as

occasion may require. Furthermore, it will be observed that when theside guards are formed separately from thel bed bottom they may, ifdesired for any reason, be removed,

from such bottom by disconnecting 'the same from the upstandingsuppprting brackets carried by the bottom and yfdisconnecting the samealong the bottom edges thereof from the bottom at the points Where suchconnection is made, and it will be-observed vthat Where the tensionimparting means `is 'located laway from the -e-ndsof the side guardssuch side guards may be more easily disconnected from' the upstandingprojections than would be the case if the helical springs were locatedat the ends of the side guards, for the reason that it would be lessdifficult for the user to unhookthe ends of the side guards from theupstanding projections'than it would be to u-nhookthe helical springsthemselves, in yvievvy of the 4fact that thosel portions of the side'guardsAbetween the springs andthe upstandingjgprojections,

- could be more easily handled owing to their flexibility than could thesprings themselves.

of these side guards the hair orother stuffed mattress will bemaintained in position when lthe same is placed on the spring mattressso that` the lateral `shifting or spreadingfof such stuffed mattress isprevented. Therterm fabric as used herein is intended to mean anysuitable structure whether made up of'linls or criss-cross membcr's orof relatively long lengthwise-extending members connected by short linksor members, or any structure which' Would y serve the purpose of a Wovenfabric; i,
